Not to forget the shorter shaft (5mm shorter on the S) giving it less length to flex on swing. Rudimentarily, with the S having lesser head weight than the D, 5mm shorter shaft, and constant swing momentum (same user, as a constant assumption), it may give the impression that with X amount of swing speed, the head is less likely to flex/bend than the D, hence giving better control, which is what the S is more about. Not at you LiteBulb, but just my thoughts below: Rather than blasting the poor dude for saying something that's not accepted by the general widespread public, maybe we can delve into why that dude says what he says. Unless it's someone whose nick rhymes with Ferrero Rocher (*chef kiss, what a chocolate) and constantly asking what grip, racket, and string/tension a pro uses all the time. I think it's safe to say not everyone has LD's level of feel and touch, so one man's meat could very well be another man's poison. In the same way I never liked the DZS and found it lacking headfeel, but I have friends who swear by it. Marmite, too.
